Most Japan guides are written for visitors from the US or Europe. If you are coming from Indonesia, the things that matter most are different: how you enter, halal food, and somewhere to pray. Here are eight to sort out early.
| Indonesia | Japan | |
|---|---|---|
| Visa / entry | — | Visa-free 15 days with a registered ePassport; otherwise a visa |
| Voltage / plug | 230V, Type C/F | 100V, flat-pin Type A |
| Transit card | KMT / e-money cards | Suica / PASMO / ICOCA |
| Food | Halal widely available | Halal is limited; pork and alcohol common in sauces |
| Weather | Tropical | Four seasons, cold winters |
1. Register your ePassport, or apply for a visa
Indonesian passport holders can enter Japan visa-free for up to 15 days, but only after registering an ICAO-standard ePassport with a Japanese embassy or consulate in Indonesia. The registration must be done before you travel and stays valid for three years or until the passport expires. If you hold an older non-biometric passport, you need a visa instead. Either route takes time, so start early.
2. Halal food takes planning
Halal restaurants exist, especially in Tokyo, Osaka, and Kyoto, but they are far fewer than at home. Pork extract, lard, mirin, sake, and alcohol are common in sauces, broths, and even snacks, so check ingredient labels and ask before ordering. Seafood and vegetarian options are a practical fallback.
3. Find prayer spaces in advance
Dedicated prayer rooms are increasing at airports, large stations, and some malls, but they are not everywhere. Search for prayer rooms along your route before you leave, and carry a small mat.
4. Bring a plug adapter
Indonesian round-pin plugs will not fit Japan's flat-pin sockets, and voltage is 100V against 230V. Most phone and laptop chargers are 100–240V and only need a plug adapter; check single-voltage devices.
5. Your local transit card will not work
Indonesian e-money and commuter cards do not work in Japan. Use Suica, PASMO, or ICOCA, which work across most of the country. See our IC card guide or set up Suica on iPhone.
6. Pack for the cold
Winter is properly cold, and even autumn and spring evenings can be chilly. Bring layers, a warm coat in winter, and check the forecast for your dates.
7. Cash still matters
Small restaurants and shrines are often cash-only, so carry yen. See cash versus card.
8. Be quiet and tidy in public
Phone calls on trains are rude, public bins are scarce, and tipping is not expected. See how not to cause trouble in Japan.
Where to go next
Choosing a base? Read Kyoto or Osaka. For data, compare eSIMs.
Do Indonesians need a visa for Japan?
Not if you register an ICAO-standard ePassport with a Japanese embassy or consulate in Indonesia beforehand — that gives you up to 15 days visa-free. Without a registered ePassport you need a visa. Confirm the current process officially.
Is halal food easy to find in Japan?
It is possible in big cities but much less common than in Indonesia. Check ingredients and ask before ordering.
Can I use Indonesian transit cards in Japan?
No. Use Suica, PASMO, or ICOCA.
